For static power save, the actual intervals are calculated by driver based on the default table and DTIM flag, then sent to uCode when the scheme is changed. Three tables are defined based on DTIM period. 1. DTIM 0 - 2 2. DTIM 3 - 10 3. DTIM > 11 The actual number of DTIM a station may miss may not exceed the following: . Only 1 DTIM may be skipped at PI=4 when allowed . Only 2 DTIMs may be skipped at PI=5 when allowed . DTIM may be skipped only 5 sec after last activity . DTIM may be skipped only 30 sec after connection establishment Only allow user to override the power_level when rf is ready to make sure power level gets changed upon request.
